From testing using my Assault Rifle build, I have not come across any instance where my damage over time effects result in critical hits. I am able to critical hit with the abilities that apply the damage over time effect, but not the effect itself.

Tested using Anima Shot with the Coagulant passive ability.

In addition, damage over time abilities do not count as a 'hit' when they tick, they don't appear to be able to 'miss' but they will not proc 'on hit' abilities. I have tested this using both the Explosive Experts passive and the Lethality passive - in both instances the ability that applied the damage over time effect would proc the passive, but the damage over time effect itself would not.

Regarding the afflicted state queries I will have to get back to you on those, I don't appear to have any abilities matching those descriptions yet :)
